certainly not. Charles Shultz hasn't been dead that long, since 2000. According to Wikipedia, as a general statement, "Typically, the duration of copyright is the whole life of the creator plus fifty to a hundred years from the creator's death,"

why? The line is vertically shifted, so that the midpoint between the peaks and valleys is not at zero, where the equation says it should be. There's nothing tricky about it, unless you are trying to make some awkward justification for the zero point not being on the wider horizontal line.

Not only that, but a company called Iconix bought the rights to the copyright in 2010. So no telling when the copyright would actually end. But it certainly isn't soon.

That equation has no vertical shift. The (x+.7) term causes a horizontal shift.

The graph on the shirt has poorly chosen axes at best (other posts mention setting the bold line in the place typically associated with zero to another value and scaling the units on the y-axis), but is mostly just wrong.

What discipline are you taking and at what school? I'm also an EE and even if I had gone the digital route, I would have had to deal with sinusoids in one way or another at least with emag. That assumes no one ever mentions dispersion and how it affects high speed digital signals. In fact, I have a hard time thinking of a single major that doesn't deal with harmonic motion in some sense.

Also, this shirt is amazing. This would go great with the trombone teacher wah wah shirt.

As a math instructor who wears a lot of mathematics-related shirtwoot tees to class, I am saddened by the fact that the axes are not labeled and the equation does not match the graph. I REALLY wanted to buy this shirt.

On a more pessimistic note ... as a graduate of the US public school system, I am unfazed by the number of erroneous "corrections" supplied in the comments and hope we all get at least a B-.

I could get into Aristote and the concept of representation.

The suspension of disbelief works for something like "in the future, we'll have spaceships with Warp Factor Plaid" or "if there were fairies, they would be able to throw a fairy dust football at my tv to give me a new football package", not for something like "Let's use a mathematical formula that produces a curve, but let's not bother to make sure the equation would actually produce a curve that matches the one that we put on the shirt."
